All our devices have started giving the warning that the push notification service cannot be reached today. We don't use a proxy server and are not blocking the connections, no changes have been made on our end.
When clicking the link in the notification for information on the firewall settings I get error 403 from the support.eset.com web server. When trying to contact support from a different network I get error 504 from the eset web server.
The ESET status page says everything is operational
